What is the fastest way to copy a DVD’s?

I was wondering what the fastest way would be to copy a non-protected (4.3gb) DVD?

Currently I am using DVD Decrypter to copy the DVD to my hard drive from there I use Nero to copy it to a disc? Is there a better/faster method in making a copy? (Decrypter rips a DVD faster than Nero)

use dvddecrypter in iso mode, than burn with dvddecrypter/imgburn
